Background: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a condition, the aetiology of which remains controversial, and there is still no consensus on its nature and determination. It has rarely been studied in post-mortem examinations, despite increasing evidence of abnormalities from neuroimaging studies.

Aim: To ascertain the feasibility of developing a national post-mortem ME/CFS tissue bank in the UK, to enhance studies on aetiology and pathogenesis, including cell and tissue abnormalities associated with the condition.

Methods: The case study was carried out combining qualitative methods, ie, key informant interviews, focus group discussions with people with ME/CFS, and a workshop with experts in ME/CFS or in tissue banking.

Results and conclusions: The study results suggest that the establishment of the post-mortem ME/CFS tissue bank is both desirable and feasible, and would be acceptable to the possible tissue donors, provided that some issues were explicitly addressed.
